This is what I did to resolve my Broadcom wireless issues on a laptop:
do the following in terminal in your "/home/*user*/downloads/" directory...
sudo apt-get install b43-fwcutter
click on this link and download this file: http://mirror2.openwrt.org/sources/broa ... .5.tar.bz2
tar xf broadcom-wl-188.8.131.52.tar.bz2
sudo b43-fwcutter -w /lib/firmware wl_apsta.o
I edited as administrator the "/etc/modules" file and found that the "b43" module was in fact spelled in Upper Case letters ("B43), so I put the letter "B" in lower case and saved, the drivers load every time I boot.
The above solved my broadcom wireless issues. PLEASE EDIT THE SUBJECT LINE OF YOUR INITIAL POST AND ADD "(SOLVED) TO THE SUBJECT LINE IF THIS RESOLVES YOUR ISSUE.
